Welcome to motorhome nightmares. When I first got our Newmar Class A gasser on a Ford chassis I started looking for a Ford dealer to service it. None of the dealers within 50 miles would offer to service it beyond simple oil changes / lubes and basic inspections and that was only one of the 15 or so dealers. Even called the Ford hotline and every dealer they stated would service it, would not. Ended up going to an independent truck service center.
I asked the local CW and they were no help. I asked who to you send your customers to for service. Got blank stares.
Basically you are on your own.
